`Om Ganeshaye Namah`
hi all,
this is metalloid, i am starting a blog for the curious kind, the ones who seek answers and no one is there to guide them. well i might too deprive you of the answers you seek but i, for sure, will point out in the right direction to look out for it, coz i seriously believe that solving our own problem helps us rather than having someone else provide us with it.
here you can post you quries and problems and we all will discuss it and try to sort it out.
i am waiting for yr questions. so pour in and start exploring.
happy rigging.

hey hi...
ReplyDeletei hv done ribbon spine but i am not satisfied with that. can u pls give an idea of it...basicaaly i am having problem related to its set up.....i hv applied follicles and joints but i am getting problem while giving its controls...and while applying in any rig.
ribbin spine is nothing, its just an indirect rig, the main demerit is that its constraint based, and when constraints come in play so does flippin, when the primary axis makes a 180 the whole thing flips, its because of the world and local coordinates, the constraints solve on world coordinates. they have nothing to do with the rotation values and thats not good. try and find alternate solutions to constraints and one more thing, try and get the concept of hierarchy clear. it'll help you a lot in creating rigs.
ReplyDeleteanyway what problems are you getting while giving its controls and while applying it in any rig?
please elaborate yr problems a little more
actually problem is that when we are givivg aim constraints to locators with up vector (object up rotation)then it get flips but when i m not applying up vector then its working properly.so i actually want to knw what is use of giving object rotation up in aim constrains.
ReplyDeletehey hi can u pls give me idea of 3 bone ik/fk switching.....without using mel..coz my mel is not wrking properly..
ReplyDeletehi aditi, the three joint chain ik/fk works just like ne other method, the difference is that there are three joint chains, instead of two, one ik driver chain one fk driver chain and the last is the skin chain. they are copies of the same chain.
ReplyDelete1)create a joint chain and duplicate it twice,
2)prefix the original chain as the skin_
3)prefix the first duplicate and the fk_driver_,
4)prefix the second duplicate as the i_driver_,
5)select the ik_driver_joint_1 and the skin_joint_1 and add orient const, then select the fk_sriver_joint_1 and select the skin_joint_1 and add orient constring.
repeat the same for the other joints.
yor setup is complete now you just have to alter the modes according to the ik/fk mode you want, for this use set driven key.
1) make a group and add an attribute to it named ik_fk_switch with limits from 0 to 1,
2) load the attribute as a driver in the set driven key,
3) load the constraint of the first joint and select the two weights,
set the value of the ik_fk_switch to 0 and the weights as 0 and 1, hit key, next, change the value of ik_fk_switch to 1 and set the weights to 1 and 0 and then again hit key.
this way you can create a switch between yr modes in 3 joint chain ik/fk system.
i hope that i have understood yr problem appropriately if not, let me know i'll post again.
hi prakritish, this flipping is a problem in use of constrains, well u will have to use the object rotation up when u add the aim constraint coz the aim affects the two rotations and leave the third to follow the world, in other words the constraint does not have any control on it, which is not good for a rigger, so u need to bound yr constraints as much as u can, adding an object rotation up as the controller of the third orientation u get control over the last rotation too.
ReplyDeletebut flippin still happens, this can be resolved to some extent by the proper use of hierarchy, if u keep the master and slave node in the same level of hierarchy and under the same parent the chances are very less that they'll flip, but to do so u must understand how the hierarchy setup works in maya. u cannot go very far without the help of hierarchy.
take care
yup u are right i will get the ik / fk switch from this method but the problem is that in this when i will switch from fk to ik then it will go to ik default position which i dont want.actually i want that if i switch fom fk to ik then ik should snap to fk pose only instead of default position .hope u are getting my problem.
ReplyDeletehello i have read the message you gave in orkut maya rigging forum..that is only i was trying to get using constraints which i tried but was not possible without using mel.yup me too deleting the constraints after applying it in mel.and those are working too but sometimes its giving problem while switching from ik to fk.and yeah in my situation also due to pole vector it was causing problem but i saw that it was bcoz of ik chain getting rotation value after applying pol vector so after fixing it that problem was not coming any more.
ReplyDeletehi aditi,
ReplyDeletea simple alternative to look out for is to have the pole vector control object parented to the fk shoulder, but using constraints on top of keyed channel causes one more problem that is pair blend and i have no clue of how to determine the order of the pair, thats one more concern while using constraints to drive the controls, neway, i override this problem i wrote scripts to constraint them to each other, but not lock them, u can say that i wrote my own pointconstraint and orient constraint but i did not lock the channnels this way they can follow each other and yet have their channels free, but as i told you there is a slight jerk in the pole vector, i have to fix that, its almost done, right now i am not getting enough time to spend on my pc, neway its good to find ppl who r interested in rigging.
my orkut is blocked so now i wont be able to access orkut.

hello...
ReplyDeleteactually i am tryin to get auto clavilce with this ik/fk system,,,but its creating lot of prob,,,hmmmm do u have any solutionn.....(hmmm actually i am try to have both manually controll of clavicle and autoclav too..and one more thing to ask should auto clav also work while its in fk mode????)
sorry i did not follow this auto clavicle. tell me what do u want to do? do you want yr clavicle to follow the orientation of spine along with a clavicle control with a switch to shift weight from spine to control. is this what you want to do or is yr prob something else?
ReplyDeleteif this is your problem then just use a couple of orient constraint with the spine tip and the clavicle control as their targets. plus you can also add the pelvis as a target if you want to lock the clavicle with the pelvis, to control this all you need is an attribute with values as 1-spine, 2-clavicle_Control, 3-Pelvis. thats it, is yr prob is something else. pls elaborate it once more.
take care
to get this auto and manual control all you need is to place yr controls in proper hierarchy, that's all. you wont have to worry about the garbage values, the parent child hierarchy will take care of it and you'll have the control there to change the value for further manual tweak.
ReplyDeletehmmm no i dont want to follow it to spine...i want clavicle bone to follow the hand bones..i also preffer it to wrk manually but i have heard its demanded in the rig to have auto clavicle too.....otherwise animotrs have to adjust its manually...
ReplyDeletethe position or the orientation?
ReplyDeleteorientation .........
ReplyDeletehmmm...again a catch, do you want the orientation of clavicle to follow the hand or do you want them oriented the same way, example, if yr char's hand moves the chest moves towards it like an aim constraint, or do you want the clavicle to be oriented as the hand is?
ReplyDeleteNo i dont want chest to move like an aim constraint..i want if charcter hand moves then clavicle bone should moves with it automatically..that means i want that clavicle bone should follow the orientation of hand...hope u are getting it ........
ReplyDeleteits not orient, its the distance, what you are trying to do is to achieve the puling of character, isn't it? you want to pull the hand controller and you want the shoulder and the rest of body to follow the hand, just like the fbik in maya, hmmmmm, i have seen the way it moves but i dont have ne clue of how it is done. as far as i think it'll involve a lot of scripting. i haven't touched all these things yet, first i want to clear all my basics and other stuff, like rotate pivots and all those things, after that i'll get down and dirty with this stuff, this is the real deal; the fbik. but still fbik is not foolproof, there are a lot of problems in fbik. but neway.
ReplyDeletetake care
nooo i m not going that advanced.may be you are not getting wat actually i am trying to say..okie have you had a look at devil rig which was uploaded in highend 3d..that rig is having autoclavicle..and there is also control given to handle it manually.that is wat i am trying to get.
ReplyDeleteok, i'll check it out.
ReplyDeletehey metalloid i am new to ur forum........
ReplyDeleteCOMMENT
i had a character with separate body parts........
i mada blend shapes and applied........
PROBLEM
i have a character prepared in one mesh.......
i dont want to rig the face with bones in the main body for facial expression.....
i want to prapare blend shapes separately for this face............how to do.....
actually what i tried is i duplicated the body and created facial expressions and applied.......but ts giving some undesirable effects...........plz help.......
even i wanted to know how to mirror blend shapes.....plz try to help me.......it may help me in my demo
hmmmmm, first of all you need to mention whether you applid blend shapes before or after merging the character's mesh. in such scenario the blend shapes need to be applied before merging the mesh. and as it suits you, you can rig the face separately or u can use just blendshapes. thats totally up to you.
ReplyDeleteand about mirroring the blend shapes, watch the watchman rigging tut from digital tutors, its given there.
take care
i applied after skinning................
ReplyDeletebut tell me what to do know.........
plzzzzzzzzzzzzzzzzz
that you will have to find out, i do not believe in spoon feeding. i will only tell where to look for your answers, i am not going to write them for you.
ReplyDeletethanks for ur advice...............
ReplyDeletehi metalloid,
ReplyDeletecould you please tell about the use of Dynamics in
Rigging.......
sure neet.
ReplyDeletewhat do you want to know?
personally i dont use dynamics is my rigs, i use deformers to deform the objects, but there are other ways to use dynamics in rigs.
whats exactly in yr mind?
feel free to ask.
hope to hear from you soon
take care
hi metalloid,
ReplyDeleteactually i want to know, is their any use of hair, fur or cloth in rigging?
yupp there is a lot of use. these are just tools, how to use them is totally up to you. see hair deforms a curve and the carve has cvs, u can use that curve to animate a tail or a hair strand or a tantacle, same goes for cloth, but i dont think that cloth should be used in this way, coz it need a considerably high amount of vertex count to function properly, but yeah hair can definitely be used as a deformer. u should follow the modular approach.
ReplyDeletetry and find out stuff on modular approach. u'll find this stuff, in object oriented programming reference books. i am not asking you to learn programming but having a lil know how of the concepts will help in yr rigging work flow.
take care
happy rigging
Thank you very much metalloid its really helpful........but as you said programming, how much it helpful in Rigging?
ReplyDeleteit helps a lot, if rigging were cooking then programming would be salt. you can always cook without salt but the food will never taste good. you have to have salt in it to make it taste good.
ReplyDeleteprogramming is must of rigging artists. it is the difference of "extra" between the ordinary and extraordinary.
take care.
the way you explained is really tasteful.
ReplyDeletebut where should the beginner start from to learn programming(mel)? means what should he learn first
a beginner should first learn the basics of programming i.e. c language and if possible you can try out unix shell programming, this will help you a lot. when i say a lot i mean a lot. these are two different platforms with different conventions if u do these two then you can do any kind of scripting.
ReplyDeleteif u want to know anything else you are most welcome.
could you please tell me little bit about Unix shell programming.is their any prerequisites required for it.is their any tutorial for it.
ReplyDeleteno there is no prerequisite for it, you can start at any point of time, what matters is how far do you take it. i would suggest to learn "c" first and then unix shell programming.
ReplyDeleteunix shell programming is a lot like Ms-Dos, but it has a lot more to it than dos. you can do stream manipulation, you can query and a lot of other things. but first you'll have to learn c.
thank u very much, one thing more to ask if you don't mind is that after learning C Will MEL be easy to learn?
ReplyDeletemel would seem like a piece of cake.
ReplyDeletehi metalloid, I am new in this blog and this blog is very good.
ReplyDeleteActually I want to ask question, actually it's not related to rigging but it related to rigging artist.If I have a permission for this then can i ask?
ya go ahead and ask.
ReplyDeleteI want to ask u about the future/career as a Rigger Artist and Importance of a Rigger Artist.
ReplyDeleteI asked this question because I heard that there is not much opening for the riggers because for one project just 5 riggers will work ....Is it true?
yes it is indeed true. there is not always openings for rigging artists because the company never disposes its rigging artists, until they themselves quit, so its a lil difficult to get a job as a rigging artist plus one should be technically very sound to be in the race.
ReplyDeleteits a very important job, rigging artists are quite respected in the industry coz what they do is not artistic and its far beyond the reach of most of the peoole, the career is quite bright and full of opportunities, but you need an initial break, once you get placed then its totally upto you how much you shine. In the beginning you'll be exploited a lot, but thats a good thing, the more exploitation the more you learn. once you have proven yr worth you can put forth yr demands but at the beginning you'll be like a beggar not in the demanding position. though this is temporary, you'll have to live it. later things will improve.
when i started i was very nervous, even made some mistakes during the test but they liked my flexibility and interactive nature. i was hired at 10,000 which is still the same. i am waiting for my appraisal, yet, which i think i'll have to wait for some more, due to this recession. neway, my team likes me and i have become an important part of it. Its nothing like that ne1 is less important, we all have our responsibilities and no1 can take their part lightly, we all must give our 100% then only the job will be done, right from the concept artist to modeler to texturing artist to rigging artist to animator to lighting artist to compositor to sound mixer. every1's job is important and each is respected. its not yr designation its the work you do marks yr identity and commands respect.
thank u very much metalloid, for giving your time for this question and u explained it so professionally.
ReplyDeleteOne thing more to ask i.e about the stability of the job.Because as the rig complete means now their no work left for him...I think so. I am little bit confuse here...So, please please clear this also.
same goes for modelers, texturing artists and animators, no1 is safe if you think this way. this is a factor that no1 can explain. sorry. but i will suggest to channel all of your energy into one direction instead of dividing it into multiple sources.
ReplyDeletethanks and sorry if i asked the wrong question but i think this one would not i.e
ReplyDeleteWhat are the main concept for a rigger artist that he must learn/concentrate on to make his skills great?
creativity. thats the most important skill and that i cant tell you coz yrs is different than mine. all i know is that one has to be very creative with the thoughts, there is no right or wrong way in rigging, if it takes to where you want to go then your method is probably right.
ReplyDeletehello sir, sir i am fresher in 3d field and right now very depress because i have read one discussion regarding today scenario of 3d field, they people discussed that their is no jobs left in this field.companies are fired the artist, if their are some job then companies offer only 3 to 5 thousand in metro cities.they suggest to walk out from this field and do some other thing.
ReplyDeleteSir do u have any suggestion?
hi amit, i am not going to lie to you. situation is quite bad right now, but this is temporary, people have lost their jobs and its not a good time to look for a job specially for a fresher. utilise this time to cultivate some more skills. dont think that animation is over in india. its still there but a bit slow. yupp in delhi there are no jobs left and the ones that are there they are not paying much.
ReplyDeleteall i can say is: dont lose hope, stay put, keep learning new stuff and continue with what you were doing, do not change yr area of interest. just hang on, this all will be over in 6 months. dont walk out. hang on.
best of luck.
tell me something more about yorself, what do you do? where are you and what are you doing?
you said it would take 6 month to change means more 6 month means more gap.actually i already have a gap of 1 year.will this gap not create a problem to me in future for job?
ReplyDeleteactually i have completed my course of 3d animation last year but after completion i wasn't understand what should i do therefore i
was wandering from one area to another sometime modeling,sometime animation etc. but didn't get anything properly therefore i wasn't able make my show reel to submit it in institute for certificate.
now i am learning Rigging from last 4 to 5 month and i am serious about it and i am living near ghaziabad(U.P)
now there is a gap, no certificate, just trouble.....in my life
i don't need sympathy because it just because of me only but i need a motivator
see, that is a problem, but if u come up with stunning stuff no one is going to ask about this gap. tell them that you were cultivating some other skills. make an animation shot, like the fighting sequence in kung-fu panda. or a rig rik horton hears a who, or anything, but utilize this time for doing something extraordinary. dont waste time on negative thoughts. believe in yourself and work hard.
ReplyDeletedont worry. keep fighting.
if possible upload yr work on youtube or mail me at satyajit.das84@gmail.com, i can guide you.
god bless you.
could u please tell one more time about the rig that u were talking about, sorry i didn't get it
ReplyDeleteand one thing could u please recommend me some good tutorials to learn about Rigging to make the skill up to level....
which rig?
ReplyDeletei did not get you.
please tell me more about the rig.
are you talking about the horton hears a who one?
ReplyDeletefirst of all: have you watched this movie?
if not then watch it as soon as possible. it has a free joint type setup. the most sought after ribbon spine rig. try to learn some more about it.
hi metalloid, i have read the question asked by amit regarding gap, i have also the same question to ask i.e if a person have too much of gap(2 to 3 year) then will the career get off? or what type of problem he will faced?
ReplyDeletesee it depends on you, if you wated yr 2-3 years then its a waste but if you spent it in cultivating new skills and learning new stuff then its ok, but if u were at home or doing something else then yes dude, yr a goner. you have to show the result of the work you did in 3 years, coz 3 years means a lot.
ReplyDeleteits not 3 year but its near to 2 year and i am learning regularly from the last some months but the speed of learning is not good but i am trying to make it speedy
ReplyDeletelook on the internet, download respective tutorials and start learning. yr faculties cant teach you what these online tuts do, coz yr very own amazing faculties learn from these tuts before teaching you.
ReplyDelete
